Extradition is like playing a game of tag, but with countries instead of people. If someone has done something bad in one country and then moves to another country, the first country might ask the second country to send that person back so they can be punished for what they did.
Here in Australia, we have laws that say when another country asks us to send someone back to them, we have to check whether it's fair and legal for us to do so. We don't just agree to send them back right away without making sure it’s the right thing to do.
There are some rules that have to be followed before we can send someone back. For example, the person must have broken a law that's also a crime in Australia, and the evidence must be strong enough to prove that they did it. There are also some exceptions, like if the person might be hurt or killed if we send them back, or if they're being asked to go somewhere where they're not allowed to have a fair trial.
So, it’s like when you play a game of tag with your friends, you have to make sure everyone follows the rules or else it wouldn't be fun. That is what we do with extradition law in Australia. We follow the rules to make sure that we're being fair and doing the right thing for everyone involved.
